摘要	In order to investigate the corrosion of pipeline materials in Seabed Sediment (SBS) environment, weight-loss and electrochemical measurements in saturated sand and mud cells with seawater were performed for a simulation. The used electrochemical measurements included linear polarization resistance (LPR) and potentiodynamic scanning measurement. It was showed that the corrosion rate of mild steel in the present condition was lower than the corrosion rate of other marine environment corrosion zones of it; that the granularity of SBS could affect the corrosion behavior greatly; that with increasing grain size of SBS, the corrosion rate increased. Integrated over the results of the weight loss and polarization curves, the oxygen diffusion (oxygen as a depolarizant agent) mechanism was proposed and discussed.; In order to investigate the corrosion of pipeline materials in Seabed Sediment (SBS) environment, weight-loss and electrochemical measurements in saturated sand and mud cells with seawater were performed for a simulation.
